The video clip on the left was obtained in the cardiac cath lab
as the right coronary angiogram was recorded in the LAO projection without
a caudal or cranial tilt, i.e., at zero degrees. The movie clip demonstrate both
a "video" representation (coronary angios, as they appear on playback
in the cath lab) and the "cine" or cineangiographic equivalent as seen
on the developed film. The two views correspond to the negative and positive
prints of photography film. You can toggle back and forth between the
two views by clicking on the respective button. You can also click a button
to see a labeled freeze frame of the coronary angiogram.

The photograph
on the top left left shows the x-ray tube, image intensifier/camera assembly
in the LAO 40 degrees angulation with no caudal or cranial tilt (0 degrees).
The adjoining photograph shows the camera's view of the patient's torso
and heart. The size of the latter has been exaggerated for purposes of
illustration.
